There may be a mistake here in thinking of colorblindness as a homogenous entity. There are many kinds of colorblindness, red and red-green colorblindness being among the most common forms, but even within this group there are several variants of red and red-green colorblindness, some of whom purportedly see colors that those with normal vision do not. Magenta, turquoise and blue are supposed to be easiest to distinguish for the majority of individuals with color blindness (despite the existence of persons with yellow-blue colorblindness). As a side note, that fact that kphoger's coworker happens to be female is fascinating because far fewer females than males are affected; most types are X-linked recessive although some more rare variants are linked to a chromosome 7 mutation.
I can't begin to speak to any aspect of color-rendering on computer monitors and any relevant info therein, but I'm sure others on this forum can do so.
tl, dr: I think kphoger's coworker's experiences are relevant and worthy of discussion, I just want to interject the caution that not everyone (maybe no one) experiences colorblindness in the same way. So what's true for her may or may not be true for other colorblind users of the forum.
